How to know when piercing is fully healed?

So I’ve had a industrial piercing for almost a year a half now. That whole time I’ve had nothing but trouble with it, such as one hypertrophic scar after another. For about the past month, I’ve been using H2Ocean on it on a regular basis, which has resulted on my last scar disappearing completely.

I feel as if my piercing is like 99% healed, but what would you say are the most telling signs that it is completely healed?

I’ve noticed it doesn’t hurt to lay on it anymore, (I’m still terrified though 😂😂). It also doesn’t hurt to move the bar around anymore. And lastly, it doesn’t hurt when it gets pulled or bump around, or when I wear a towel on my head to dry my hair!
